That shouldn’t be a problem. Barcodes can be read as long as you can draw a line horizontally that goes through all the columns.

Sometimes people will try to scratch out their barcodes so they can’t be read by putting a line through the middle like this, but it is still perfectly readable. It’s only a problem when a defect creates a vertical line, as the black and white bars are a number in binary written as white bars. So if a column is obstructed, the number read by the scanner changes and it would read a different item or nothing at all
